Sesamoid Avascular Necrosis and Stress Fracture Treated with Core Decompression and Biologic Augmentation.

Sesamoid bone disorders are disabling conditions with limited treatment options. This case report describes a 17-year-old football player with avascular necrosis (AVN) in both the tibial and fibular hallux sesamoids with a concomitant non-displaced stress fracture of the tibial hallux sesamoid. After a short period of conservative management, the patient underwent open sesamoid core decompression with an application of concentrated bone marrow aspirate and amnion matrix. After postoperative physical therapy, the patient achieved a painless range of motion of the first metatarsophalangeal joint. He returned to full athletic activities by 6 months postoperatively. Core decompression with biologic augmentation is a viable treatment option for sesamoid AVN. Earlier surgical intervention for sesamoid AVN can also be considered, particularly in younger active patients.

Cookiecutter Shark-Related Injuries: A New Threat to Swimming Across the Ka'iwi Channel.

In a 5-month period in 2019, 3 long-distance swimmers sustained cookiecutter shark-related injuries while attempting to cross the Ka'iwi Channel between the Hawaiian Islands of O'ahu and Moloka'i. This report is the first case series of cookiecutter shark bites on live humans. A retrospective review of the State of Hawai'i Division of Aquatic Resources Shark Incidents List was conducted between March 1, 2019, and July 31, 2019. Trauma registry data and medical records were reviewed in patients treated for cookiecutter shark bites at The Queen's Medical Center in Honolulu, Hawai'i. All 3 patients sustained nonfatal cookiecutter shark bite circular wounds measuring between 8-13 cm in diameter. They were injured swimming over waters with depths of greater than 2000 feet at night. Patients had prolonged transport times to the emergency department (ED), averaging 73 minutes, due to their injuries occurring on the open water. All were hemodynamically stable upon ED arrival and did not require blood products. Tetanus toxoid was updated, and prophylactic antibiotic coverage, including doxycycline for Vibrio spp., was administered. Two of 3 patients were treated with operative management. Open water swimmers crossing the deep waters between the Hawaiian Islands at night are most at risk for cookiecutter shark bites. Wounds may penetrate down to and through the fascial level. Immediate life-saving hemorrhage control administered by personnel accompanying the swimmers on the open water is important for preventing morbidity and mortality. Antibiotic prophylaxis for marine bacteria is recommended.

Shark-related injuries in Hawai'i treated at a level 1 trauma center.

BACKGROUND: Although rare, human-shark interactions can result in a wide spectrum of injuries. This is the first study to characterize shark-related injuries (SRIs) in Hawai'i. METHODS: This is a retrospective review of the State of Hawai'i Division of Aquatic Resources Shark Incidents List between January 1, 2009 and December 31, 2019. Trauma registry data and medical records of patients treated for SRIs at the only level 1 trauma center in Hawai'i were reviewed. RESULTS: Sixty-one patients sustained SRIs in the Hawaiian Islands: 25 in Maui, 16 in O'ahu, 12 in Hawai'i, and 8 in Kaua'i. In cases where the shark species could be identified, tiger sharks were the most frequent (25, 41%). Four cases were fatal-all died on scene in Maui with the shark species unknown. Forty-five survivors (79%) received definitive care at regional facilities. Twelve (21%) were treated at the level 1 trauma center, of which two were transferred in for higher level of care. Of the 12 patients, 11 (92%) had extremity injuries, with 3 lower extremity amputations (25%), 2 with vascular injuries (17%), and 5 with nerve injuries (42%). One had an injury to the abdomen. All patients had local bleeding control in the prehospital setting, with 9 (75%) tourniquets and 3 (25%) hemostatic/pressure dressings applied for truncal or proximal extremity injuries. The mean time from injury to emergency department arrival was 63 minutes. DISCUSSION: Most SRIs are managed at regional facilities, rather than at a level 1 trauma center. Prehospital hemorrhage control is an important survival skill as time to definitive care may be prolonged. For cases treated at the level 1 trauma center, nerve injuries were common and should be suspected even in the absence of major vascular injury. Correlating shark behavior with observed injury patterns may help improve public awareness and ocean safety. LEVEL OF EVIDENCE: Level V, epidemiological.

Implementing Regional Nerve Blocks in Hip Fracture Programs: A Review of Regional Nerve Blocks, Protocols in the Literature, and the Current Protocol at The Queen's Medical Center in Honolulu, HI.

Hip fractures are a common cause of acute pain in elderly patients. However, pain may be undertreated due medical comorbidities. Strong evidence supports the use of regional nerve blocks to reduce preoperative pain after hip fracture. Despite recommendations for their use, regional nerve blocks may not be in widespread practice in the United States. To help promote the addition of regional nerve blocks into hip fracture protocols, this paper will provide an overview of two commonly used regional nerve blocks for hip fracture (fascia iliaca compartment block and femoral nerve block), review the regional nerve block protocols presented in 12 studies, and present the detailed protocol currently in use at The Queen's Medical Center in Honolulu, HI.
